<I>In How My Family Lives in America,</I> author-photographer Susan Kuklin zeroes in on the source of cultural identity: the family. Meet: <P>Sanu, who is learning how to braid her hair and to cook the same African meal her father makes. <P>Eric, who loves to play baseball with his dad and to dance the <I>merengue</I> with his friends and family. <P>April, who works hard on her Chinese writing and tries to keep up with her family's challenging games. <P>Their stories emphasize the seemingly minor and everyday ways heritage is transmitted: stories, songs, games, language, special occasions. They show the importance of choice and adaptation in forging a cultural identity. And they provoke readers to examine their own families -- what makes them the same, what makes them distinct, and how this uniqueness is celebrated.
